Chronic stress and social isolation are frequently cited as precursors to physical illness, yet the biological machinery ...

Mitochondria are well known as energy suppliers, and powerhouses of cells, but they have other crucial functions as well. One of those functions is outcompeting pathogens for resources, according to ...

James McCully was in the lab extracting tiny structures called mitochondria from cells when researchers on his team rushed in. They’d been operating on a pig heart and couldn’t get it pumping normally ...

I always wanted to understand life. What moves us? What allows us to heal and thrive? And what goes wrong when we get sick or when we eventually stop breathing and die? My search for answers to these ...

A new Dartmouth study opens new avenues for understanding—and potentially manipulating—how cells decide to live or die.

New findings could aid future development of more efficient therapeutic strategies in the context of regenerative medicine and aging.

The bean-shaped organelles are now being recognized for their part in immune signaling, stress responses, and neural ...

People need to sleep, and sleep deprivation can cause many changes in the brain. But we have a poor understanding of why sleep is so crucial. New research has examined a fruit fly model to assess how ...

Researchers at the Max Delbrück Center have found that a cellular housekeeping mechanism called autophagy plays a major role ...
